Check Rent Increases: Tenants in Austria

Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025
Tenants in Austria often face the question of whether a announced rent increase is lawful. This article explains when you should check an increase, which deadlines and formal requirements apply, and which documents are crucial. We show simple checking steps: review the reason, compare the reference or category rent, collect correspondence and receipts, and observe statutory deadlines. The language remains practical so that even without legal knowledge it is clear which steps are possible — from a formal query to the landlord to judicial review. If you are unsure when a review makes sense, the steps in the text will help.

When to check?

Always check a rent increase when the increase is announced or a new tenancy agreement is presented. Common triggers are announced percentage increases, adjustments to the reference value or category rent, or when additional costs are passed on to the rent. Compare the justification with the lease and check whether formal requirements have been met [1]. Collect all letters, emails and receipts in case of later review.

Keep receipts organized in chronological order and date them.

Quick checklist

  • Check deadlines (deadlines) — when was the increase announced and what deadline applies?
  • Compare the justification (rent) — does the reason match the category rent or reference value?
  • Check form and delivery (form, submit) — was the increase correctly delivered in writing?
  • Collect evidence (document) — gather all receipts, photos and documents.
  • Consider legal remedies (court) — when is a step to the district court sensible?
Good documentation increases the chances of success in a complaint or legal action.

Formal requirements and deadlines

In many cases rent increases must be made in writing and include a comprehensible justification. Pay attention to the deadlines stated in the notice; incorrect delivery can affect the effectiveness of the increase. If unsure, check the legal basis or seek advice [1].

Do not miss deadlines: respond to landlord letters in time to preserve your rights.
